Biological materials cover the same range of physical properties as technical materials, and they are commonly more durable. They have the advantage that they are made of fewer components and are easily recycled. Their effectiveness relies on self-assembly of liquid crystalline structures whose molecules are stiffened by inter- or intra-molecular bonding rather than by high-energy internal bonding. Biomimetic materials cannot properly mimic such synthetic processes and use machines to assemble structures, but there are ways in which such molecular assemblies could be introduced, for instance by using a 'spinneret' based on that found in a spider or caterpillar in a rapid manufacturing machine. Design rules include hierarchy, composite structure, recyclability, controlled relaxation of parameters, and multifunctionality. We are still in the early stages of realizing such methods of manufacturing, much of it in the 'MakerBot' community. This essentially distributed approach to manufacturing seems quintessentially biological with many organisms (us) working at it with total (internet) communication with each other.
